Messenger Operating Manual

1. Introduction:

This document describes the methods to be employed when installing and connecting

equipment associated with the Messenger XL digital controlled loudspeaker array, produced

by Ateïs International S.A.

This type of loudspeaker Array is equipped with onboard amplifiers, powersupply and signal

processing boards and needs extra precaution during installation and set-up of the unit.

The Messenger comes pre-programmed from the factory and is ready for immediate use. With

the concept of the Messenger we have focussed on an easy to install and to set-up unit which

does not lead to human errors and mistakes during the installation and set-up.

The Messenger can be programmed to adapt it for special applications where a different lobe-

shape is required. For that purpose you will need a USB-RS485 interface and the M-Control

communication protocol for Windows

®.

2. General information:

The Messenger XL has the unique quality that the acoustical centre can be moved over the

array to match with required mounting heights. This can be achieved because each driver is

separately powered and processed and therefore all variations between a Symmetrical and an

asymmetrical arrangement can be made by a simple push on a button. This separates the

Messenger XL from any other line-array speaker making it the most flexible and unique line

array with software controlled directivity pattern.

Lobes

:

The Symmetrical lobe has its acoustical-centre centred in the middle of the array. The

Asymmetrical lobe has its acoustical-centre centred at the bottom or at the top of the array.

Any other position of the acoustical-centre between the middle and the bottom/top of the array

fades the lobe-shape from a purely symmetrical shape to an asymmetrical shape.

Symmetrical lobes are mostly used to address balcony areas or is used for mounting heights

of 1.2m from the floor. It results in a sharply defined directive shape with vertical opening-

angles adjustable in steps from 40 down to 5 degrees. The lobe shape guarantees an equal

coverage even when seated very near to the source.

An asymmetrical lobe are used for typical mounting heights between 1.8 and 4m from the floor

and covers the groundsection. It results in a lobe that starts at 5m distance from the array at

ear-level and ends in a sharp lobe at 40m and further.(This depends on the type of array) The

Asymmetrical lobe has the ability to keep the sound deviation within 2 dB from 5 to 60m. Its

mounting height is NOT critical and therefore it is the most used system solution. The vertical-

opening angle can be adjusted in steps from 40 down to 5 degrees.

4. Products:

The Messenger XL series of products is series of digital controlled line-arrays with constant

directivity. The series contains the following products:

- Messenger M, a 12-way digital controlled steerable array, length 171 cm.

- Messenger L, a 18-way digital controlled steerable array, length 237 cm.

- Messenger XL, a 24 way digital controlled steerable array, length 304 cm.

- Messenger Two-L, a 36 way digital controlled steerable array, length 454 cm.

- Messenger Two-XL, a 48 way digital controlled steerable array, length 608 cm.

5. System considerations:

Mounting height of the Messenger XL is NOT critical. The Asymmetrical unit can be

positioned between 1.85 metre and 4 metre from the floor, measuring from floor level

to the centre of the first driver, acoustical mounting point, at the bottom of the array.

The symmetrical array is located at 1.2 metre from the floor measuring from floor level

to the centre of the first driver, acoustical mounting point, at the bottom of the array.

The acoustical centre of the Messenger can be moved over the array from bottom to

the middle and from the middle to the top in 9-stepsd. Special pre-constructed lobes

are available as well as lobes with variable opening angles.

The bottom of the array is indicated by the part that carries the service hatch behind

which the input connection board is located. The mains and the 24 VDC connectors

are located in this position. The battery for emergency purposes should be located as

close as possible to the array to avoid power loses over the cable. The built-in charger

is able to maintain the battery. It is NOT meant for quick or for normal charging!

The position of the acoustical centre of the Messenger can be chosen from a library of

lobes available from our download site at: www.ateis-international.com

The lobes can offer you system solutions in cases where there are special

requirements on mounting position or where there are height variations in the listening

plane.

When connecting the Messenger to the mains supply, be aware that the signal earth

of the Messenger is the same as the mains earth. It is recommended that the mains is

checked and connected to a proper ground. The mains should also be uninterrupted!

If this is not the case a backup power supply can be applied to maintain operation in

case of a power failures. Check the technical details in case of a battery back-up

source and its capacity.

The audio input to the Messenger should be according to one of the following

electrical standards:

Primary input:

Transformer balanced line level signal of 0 dBu ≡ 775 mV.

Level can be electronically adjusted

Maximum recommended distance: 300 metre.

Secondary input

: (Used for Ambient Noise Microphone or optional inputboard SD-1)

→♪ Un-balanced line level signal of 0 dBu or 6 dBu.

Level can be electronically adjusted

Audio output :

←♪ This output follows the signal input 1

Page 5 of 38

Level can be set in M-Control

Messenger Operating Manual

Optional input board for secondary input – SD-1:

→♪ Transformer balanced microphone level signal of 5 - 10 mV.

The Messenger is equipped with an RS485 data-network connection, which allows

remote system set-up and control of all parameters available through the M-Control

software for Windows®. Each addressable loop device gets a unique I.D. number for

quick FIR/Lobe downloads. I.D.-numbers are chosen between 1 and 32.

A two core communication link is used to connect an RS485 serial link to up to 32

Messengers using the DATA-RS485 input and slave-output.

NOTE: - An end-of-line resistor of 120 ohm should be applied to the last Messenger

connected in the data-ring.

The Ambient-Noise-Following option is supplied in the software and needs the

hardware module SD-1 and an ambient-noise microphone. The SD – 1 is equipped

with a pre-amplifier with phantom power and uses the secondary input of the

Messenger.

The ambient temperature for the Messenger XL should not exceed 40°C. If higher

temperatures are expected, precaution should be taken to avoid this by means of

installing extra forced ventilation within the Messenger. Alternatively a Messenger

XL/WP can be ordered which has the electronics externally installed in box. This unit

must be placed in a conditioned room.

2 potential-free OUTPUT contacts are provided to serve the following functions:

√ No. 1 Fatal fault

√ No. 2 General fault

2 Opto-coupler isolated inputs are provide for

√ No. 1 Priority Audio input 2 activated

√ No. 2 Lobe switch

6.1. Mounting considerations:

Mounting instructions:

A: Acoustical centre When the acoustical centre is chosen in the lower range of the array,

an Asymmetrical lobe is generated. These are used in conjunction

with mounting heights between 1.8 and 4m from the floor and results

in a lobe that starts at 5m distance from the array at earlevel and ends

in a sharp lobe at 60m and further. The Asymmetrical lobe has the

ability to keep the sound deviation within 2 dB from 5 to 60m. Its

mounting height is NOT critical and therefore it is the most used

system solution. The vertical-opening angle is adjustable from 40

down to 5 degrees, with steering up to 30 degrees up and down.

The acoustical centre runs from A-symmetrical to Symmetrical, from

bottom to top in 9-steps.

H: Mounting height This height is measured between the floor and the bottom of the array

which starts at the bottom driver. (Small plate).

It is recommended to keep this height around 2mt.

D: Min. Distance This distance is measured from the front wall towards the first

listener’s position.

E: Effective range This distance is measured between the Messengers mounting

position and the last listener’s position.

Additional information:

Position: It is of vital importance that the Messenger is always placed in a rectangle

line with the listener’s plane. This ensures that reflected energy from the

back-wall stays in the acoustical centre and is not bounced into the ceiling

area where it might contribute artificial reverberation to the building

acoustics.

Opening angle: The vertical opening angle can be varied between 40 and 5 degrees.

Steering: Steering up to +/- 30 degrees.

Messenger Operating Manual

9.4.1.

The UPLOAD of a LOBE (FIR-File)

To upload a lobe, you first have to generate a FIR file from the Lobe-Assembler software.

(See section 4 of this manual). The file will carry the file extension: *.mfd (Export file from Lobe

Assembler)

Click on Upload (Lobe1 or Lobe2) and select the MDF (Messenger Fir Data)

you want to load in the Messenger.

For uploading the data into the Lobe1 section you get the following screen:

For uploading the data into the Lobe2 section you get the following screen:

Page 18 of 38

Click on send.

A running bar will show you the time remaining for the upload. During the upload the

unit will not pause its functioning, so an upload or lobe-change could be done during

a live performance. After loading the lobe click on activate.

It is advised to reset the Messenger after the upload of a new Lobe file.

The reset procedure is described in the System tab.

Messenger Operating Manual

9.4.2. Ambient noise following.

If Ambient noise following is activated the secondary input is turned into a measuring input.

This input accepts line signals. If a sensing microphone is connected we advise you to use

the SD 1 expansion input board. For all the details of the SD 1 expansion board we refer to

the appendix.

Max gain; determinates the maximum additional amplification.

Trigger level; is the point where the additional amplification starts.

The LED lights up when the trigger level is reached.

Correction; is the ratio between the level above trigger level and the increase in volume gain.

Example (correction is set at 30%):

if the Ambient noise level is 10dB above trigger level the volume gain will be 3 dB.

Speed; (slow – medium – fast) sets the reaction to changes the sensing

microphone is reregistering.

9.4.3. VOX

In this setting the secondary input can be used as alarm input.

If the audio level, on the secondary input, reaches a certain level

this signal overrides the primary input.

Trigger level; sets the point where the secondary input becomes active.

The LED lights up when the trigger level is reached.

Sustain; sets the hold time of the Vox in seconds.

9.4.4.

Ambient noise following and Vox both on.

Page 19 of 38

When those two functions are set on together the Ambient noise following function is set

with an extra feature. The Vox is now working as a threshold on the primary input.

This feature means that if the audio level on the primary input reaches the trigger level the

Ambient noise sensing is stalled at the correction value of that moment.

Messenger Operating Manual

9.4.5. Global amplifier gain:

This sets the gain of all the amplifiers. It can be set between –10dB and + 10dB.

Default setting is 0 dB.

For normal situations it is advised to keep the default setting. Only when a higher

SPL level is needed correct it upwards.

9.4.6. Design new Lobe filter.
